Description

[Detailed Description of the Invention] Purpose of the Invention Industrial Application Field The present invention relates to a device for mounting and tightening a tire anti-slip device on a tire.

Problems to be solved by conventional techniques and inventions Conventionally, a non-slip device for automobile tires has a plurality of non-slip members made of a chain placed between a pair of side strips made of a chain at intervals. was common, but recently, in addition to this,
A plurality of cross cables are connected by passing them at intervals between a pair of side strips made of cables, and each cross cable is fitted with a plurality of metal cylindrical bodies so as to be freely rotatable, or a pair of cables made of a pair of cables. A system in which multiple synthetic resin belts were connected by passing them between the side strips began to be used.

In such a tire skid device, as a device that connects both ends of each side strip and tightens it to the tire,
A connecting fitting with a hook formed at the tip is connected to one end of each side strip, and a connecting fitting to which the proximal end of the band is fixed is connected to the other end, and the tip of the band is connected to both ends of a pair of corresponding guide rods. A movable rod is slidably passed between the pair of guide rods of a rectangular locking ring connected by a stop rod and a tightening rod. It has been proposed that the locking rod of the ring is locked to the hook so that both ends of the side strips are connected to each other. This tightening device has the advantage of being easy to install and remove and can be retightened, but when installing this device, first connect both ends of the inner side strips of the tire with an appropriate amount of slack. Next, by tightening the outer band of the tire, the inner side strips are tensed, and at the same time the outer side strips are tightened to connect the two ends. ,
The anti-slip member that spans the tread of the tire may be installed with it biased towards the inside or outside of the tire, or the tension of the side strips on both sides may be different on the inside and outside. During running, the anti-skid member shifts and the side strips become loose, and the force that pinches the folded part of the band is weakened, causing the band to slide in the direction of loosening.As a result, the loosening of the side strips further increases, causing the slip device to become centrifugal. The force could have caused contact with the tire house or nearby equipment.

The present invention has been developed in view of the above points, and an object of the present invention is to provide a tightening device in which the anti-slip member is tensioned equally from the inside and outside of the tire without shifting in the axle direction. That is.

Embodiments Hereinafter, embodiments of the present invention will be described based on the accompanying drawings.

The anti-skid device shown in FIG. 1 consists of a pair of side cables 1 arranged along both side parts b of a tire a,
1, several synthetic resin bands 2 placed across the tread portion c are passed across and connected.
Both ends of each side cable 1, 1 are connected by tightening devices A, A according to the present invention, and as shown in FIG.
A first connecting metal fitting 6 is fixed to one end by caulking, and a hook 61 is formed by folding the tip end of the first connecting metal fitting 6 outward. The tip portion 62 is formed into an arc shape, and a second connecting fitting 7 is also fixed to the other end of each side cable 1 by caulking, and a bridge formed by punching is attached to the connecting fitting 7. The proximal end of an elongated cloth band 8 is bent and fixed to the portion 71, and
A binding ring 10 is fitted into each band 8, and a fastener 9 is movably attached. This fastener 9 is a fastening rod of a rectangular locking ring 91 which is formed by turning a round steel wire and connecting both ends of a pair of corresponding guide rods 91a, 91a with a tightening rod 91b and a locking rod 91c. A movable rod 92 in which a hook-shaped pressing portion 91d with one guide rod 91a extended is formed on the 91b side, and the corresponding guide rods 91a, 91a are knurled on the outer periphery to increase frictional resistance with the band 8.
By passing the tip of the band 8 from the back side of the locking ring 91 to the front side, rotating the movable rod 92, and passing it from the front side to the back side again, the band 8 A fastener 9 is attached to the.

When the movable rod 92 of the band 8 is turned and folded back, the front surface has a
"0" and "0" are sequentially arranged at positions corresponding to a pair of tightening scales 28 arranged at equal intervals on both edges from the distal end to the proximal end, and the tightening scale 28 at the center in the width direction. The numbers 38 of ``1'', ``2'', ... ``8'', and ``9'' are printed so as to match on the bands 8 and 8 on both sides, respectively, and as shown in Fig. The tightening scale 28 and numbers 38 can be visually confirmed at the distal end, and the proximal end fixed to the second connecting fitting 7 on the same surface as above has a part facing the back side. Characters 18 for "back" and "front" are printed on the parts bent by the bridging portion 71 and facing the front side, respectively.

Next, to explain the procedure of the tightening work, first, the locking rod 91c of the inner locking ring 91 is connected to the first connecting fitting 6.
Hook 61 of the band 8, check the position of the tightening scale 28 and number 38, pull the tip of the band 8 toward the second connecting fitting 7 to the specified position, pass it through the binding ring 10, and fix it. As a result, both ends of the inner side cable 1 are connected in a slightly loosened state, and then each belt 2 is placed at a central position on the tread portion c without being biased toward the inside or outside.
After that, both ends of the outer side cable 1 are connected in the same way as the inner side, and when the tip of the band 8 is pulled toward the second connecting fitting 7, the outer side cable 1 is tensed and at the same time the inner side cable is connected. cable 1
is tightened, and due to the tension, the base of the folded portion of each band 8 on both sides is pinched between the tightening rod 91b and the moving rod 92 of the locking ring 91, thereby preventing loosening. Both ends of the side cables 1 on both sides are firmly connected, and then tighten the outer band 8 to the same position as the inner band 8 while checking the tightening scale 28 and the number 38, and tighten both the connecting fittings 6 and 7 on the inner side. By bringing them close to each other at equal distances on the outside, the tension of the side cables 1 on both sides becomes equal, and as shown in FIG. It is tensioned evenly across both side portions b and is tightly attached to the tire a.

On the other hand, in order to remove the skid from the tire a, first push the pressing part 91d of the outer locking ring 91 in the direction of the When the center of rotation is caused,
The tension of the band 8 causes the movable rod 92 to become the tightening rod 9.
The guide rod 91 was pressed against 1b.
a, 91a, the force pinching the base of the folded portion of band 8 is weakened,
Because the band 8 rotates around the moving rod 92 due to its tension and slides in the direction of loosening, the locking ring 91 is attached to the hook 6.
As a result, the tension on the outer side cable 1 is released and at the same time the inner side cable 1 is also loosened, so that the inner locking ring 91 can also be easily removed from the hook 61. I can,
The removal work is complete.

Note that in this embodiment, the tip 62 of the hook 61
Since the locking ring 91 has an arcuate shape, the locking ring 91 can be easily removed from the hook 61 by rotating about an axis parallel to the guide rods 91a, 91a.

As specifically explained in the above embodiment,
The tightening device for a tire skid according to the present invention has a plurality of side strips arranged across the tread of the tire between a pair of side strips that are arranged on both sides of the tire in a substantially circular manner. In a tire skid device in which two non-slip members are connected at intervals, a connecting fitting having a hook at the tip is attached to one end of each of the pair of side strips, and a connecting fitting having a hook formed at the tip is attached to each end of each of the pair of band members. Connecting fittings with fixed ends are respectively attached, and each tip of the pair of bands is connected to the pair of guide rods of a rectangular locking ring in which both ends of a pair of corresponding guide rods are connected by a locking rod and a tightening rod. The movable rods are slidably passed around each of the movable rods of the pair of fasteners and folded back to the same side, the locking rods of the locking ring are locked to the hooks, and the locking rods of the locking ring are locked to the hooks. Both ends of the side stripes are connected to each other, and along the length direction, each of the surfaces that become the front side by folding the pair of bands,
The gist of the invention is to provide matching tightening scales on both bands, and the side cable can be tightened by simply hooking the locking ring onto the hook and pulling the band. It is possible to firmly connect both ends of the side strips such as, etc., and by simply pulling the locking ring, the band loosens and can be immediately removed from the hook, making it possible to quickly remove the tire skid device. Moreover, by tightening the bands on both sides so that the tightening scales are the same, each anti-slip member that spans the tread portion can be attached to a pair of side strips without shifting toward the inside or outside of the tire. As a result, the tension can be applied equally to both sides, so there is no loosening or shifting during driving, and the centrifugal force prevents the skids from loosening and colliding with the tire house, etc., ensuring safe driving. It has the potential to be effective.
